A preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

[Embodiment]
FIG. 1 is a schematic diagram showing a work system 10 according to an embodiment. The machine tool 10 includes a machine tool 12, a numerical control device 14, a measuring device 16, and an information processing device 18.

The machine tool 12 processes the object W to be machined using a tool. The machine tool 12 has a fixing base 20 on which a tool or the like is attached, and a table 22 on which the workpiece W is attached. In the present embodiment, it is assumed that the probe 34 of the measuring device 16 is attached to the fixed base 20.

The machine tool 12 also includes a servo amplifier 24 (24Y, 24Z, 24X, 24A), a servomotor 26 (26Y, 26Z, 26X, 26A) and a power conversion transmission mechanism 28 (28Y, 28Z, 28X).

The servo motor 26Y is a motor for axially moving the fixed base 20 in the Y-axis direction, and the servo motor 26Z is a motor for axially moving the fixed base 20 in the Z-axis direction. The servo motor 26X is a motor for axially moving the table 22 in the X-axis direction, and the servo motor 26A is a motor for changing the inclination of the table 22. The Y-axis direction is an axial direction that approaches or separates from the workpiece W, and the X-axis direction and the Z-axis direction are orthogonal to each other in a plane orthogonal to the Y-axis direction.

The rotational force of the servomotor 26Y is transmitted to the fixed base 20 via the power conversion transmission mechanism 28Y. The power conversion transmission mechanism 28Y converts the rotational force of the servomotor 26Y into a linear motion in the Y-axis direction. Therefore, the rotation of the servomotor 26Y causes the fixing base 20 to move in the Y-axis direction. The power conversion transmission mechanism 28Y includes a ball screw 28Ya connected to the rotating shaft of the servomotor 26Y extending in the Y-axis direction, and a nut 28Yb screwed into the ball screw 28Ya and connected to the fixing base 20.

The rotational force of the servomotor 26Z is transmitted to the fixed base 20 via the power conversion transmission mechanism 28Z. The power conversion transmission mechanism 28Z converts the rotational force of the servomotor 26Z into a linear motion in the Z-axis direction. Therefore, the rotation of the servomotor 26Z causes the fixing base 20 to move in the Z-axis direction. The power conversion transmission mechanism 28Z includes a ball screw 28Za connected to the rotating shaft of the servomotor 26Z extending in the Z-axis direction, and a nut 28Zb screwed into the ball screw 28Za and connected to the fixing base 20.

The rotational force of the servomotor 26X is transmitted to the table 22 via the power conversion transmission mechanism 28X. The power conversion transmission mechanism 28X converts the rotational force of the servomotor 26X into a linear motion in the X-axis direction. Therefore, the rotation of the servomotor 26X causes the table 22 to move in the X-axis direction. The power conversion transmission mechanism 28X includes a ball screw 28Xa connected to the rotating shaft of the servomotor 26X extending in the X-axis direction, and a nut 28Xb screwed to the ball screw 28Xa and connected to the table 22.

The rotational force of the servomotor 26A is transmitted to the table 22 via a power conversion transmission mechanism (not shown). This power conversion transmission mechanism converts the rotational force of the servomotor 26A into a motion in a direction that changes the inclination of the table 22. Therefore, as the servomotor 26A rotates, the inclination of the table 22 changes.

The numerical control device 14 controls the machine tool 12. The numerical control device 14 has a program analysis unit 30 and a motor control unit 32. The program analysis unit 30 analyzes the program and outputs the analysis result to the motor control unit 32. The motor control unit 32 controls the servomotors 26Y, 26Z, 26X via the servo amplifiers 24Y, 24Z, 24X based on the analysis result of the program. As a result, the fixed base 20 is axially moved in the Y-axis direction and the Z-axis direction, and the table 22 is axially moved in the X-axis direction.

When the operator performs an axis feed operation (Y-axis feed operation, Z-axis feed operation, X-axis feed operation) on the information processing device 18 side, the feed position (coordinate information) corresponding to the axis feed operation is the information processing device. It is given to the motor control unit 32 from 18. In this case, the motor control unit 32 controls the servomotors 26Y, 26Z, 26X via the servo amplifiers 24Y, 24Z, 24X so as to be in the feed position. As a result, when the operator performs the Y-axis feed operation, the fixed base 20 moves in the Y-axis direction, and when the operator performs the Z-axis feed operation, the fixed base 20 moves in the Z-axis direction. When the operator performs the X-axis feed operation, the table 22 moves in the X-axis direction.

Further, when the motor control unit 32 is given a correction position (coordinate information) for correcting the inclination of the table 22 from the information processing device 18, the motor control unit 32 sets the servo amplifier 24A so as to be the correction position. The servo motor 26A is controlled via the servo motor 26A. As a result, the table 22 moves so that the inclination of the table 22 changes.

The measuring device 16 is provided around the machine tool 12 and has a probe 34 and a measuring body 36. The probe 34 is a rod-shaped probe for measuring the distance to the object to be machined W, and is attached to the fixing base 20 with the tip facing the object to be machined W. When the probe 34 is properly attached to the fixation base 20, the longitudinal direction of the probe 34 is parallel to the Y-axis direction and has a relationship orthogonal to the X-axis direction and the Z-axis direction. It should be noted that this relationship includes tolerances generated depending on the attachment of the probe 34 to the fixed base 20 and the installation of the axes (X-axis, Y-axis, Z-axis) and the like.

The measuring body 36 measures the relative distance between the probe 34 and the workpiece W. In the present embodiment, the measurement main body 36 detects the contact pressure of the probe 34 in contact with the object to be machined W, and converts the detected contact pressure into the distance to the object to be machined W to process the probe 34. The relative distance to the object W is measured.

The information processing device 18 processes various types of information. The information processing device 18 is connected to the numerical control device 14 and the measuring device 16, and exchanges various information with the numerical control device 14 and the measuring device 16. FIG. 2 is a schematic diagram showing the configuration of the information processing apparatus 18. The information processing device 18 includes an input unit 40, a display unit 42, a storage medium 44, and a signal processing unit 46.

The input unit 40 is an operation unit for the operator to input a command or the like. The input unit 40 includes a numeric keypad for inputting numerical data, a keyboard, a touch panel, a volume knob, and the like. The touch panel may be provided on the display screen of the display unit 42.

The display unit 42 displays information, and the storage medium 44 is a medium for storing information. A liquid crystal display or the like can be mentioned as a specific example of the display unit 42, and a hard disk or the like can be mentioned as a specific example of the storage medium 44.

The signal processing unit 46 is connected to an input unit 40, a display unit 42, and a storage medium 44, and has a processor such as a CPU (Central Processing Unit) or an MPU (Micro Processing Unit). When this processor executes the basic program stored in the storage medium 44, the signal processing unit 46 includes the first acquisition unit 50, the second acquisition unit 52, the display control unit 54, the position control unit 56, the calculation unit 58, and the tilt. It functions as a correction unit 60.

The first acquisition unit 50 acquires the measurement information measured by the measuring device 16 from the measuring device 16. In the present embodiment, the first acquisition unit 50 acquires the distance measured by the measuring device 16 from the measuring device 16 at predetermined intervals. When the first acquisition unit 50 acquires the measurement information (distance), the first acquisition unit 50 stores the acquired measurement information in the storage medium 44.

The second acquisition unit 52 acquires state information indicating the state of the machine tool 12 from the numerical control device 14. The state information includes, for example, the position (machine coordinates) of the tool or probe 34 attached to the fixed base 20, the shaft feed amount and the shaft feed speed, the machining time of the machining object W, the operating time of the machine tool 12, and the spindle rotation. The number etc. can be mentioned. In the present embodiment, the second acquisition unit 52 acquires at least the position of the probe 34 from the numerical control device 14 at predetermined intervals. When the second acquisition unit 52 acquires the state information (position of the probe 34), the second acquisition unit 52 stores the acquired state information in the storage medium 44.

The display control unit 54 controls the display unit 42. The display control unit 54 causes the display unit 42 to display the measurement information and the state information stored in the storage medium 44. As a result, the operator can confirm both the measurement information and the state information on one display screen.

In the present embodiment, for example, as shown in FIG. 3, the display control unit 54 displays the distance (measurement distance) and the position of the probe 34 on the same screen. As a result, the operator desires the probe 34 with respect to the workpiece W while confirming the absolute position of the probe 34 and the relative distance of the probe 34 with respect to the workpiece W on one display screen. The axis feed operation can be performed so that it is placed at the position of. In the example of FIG. 3, the amount of change in distance is indicated by a numerical value and a gauge.

When the axis feed operation (Y-axis feed operation, Z-axis feed operation, X-axis feed operation) is performed by the operator using the input unit 40, the position control unit 56 moves the axis according to the axis feed operation. In addition, the machine tool 12 is controlled.

That is, the position control unit 56 generates a feed position (coordinate information) according to the axis feed operation of the operator, and outputs the generated feed position to the motor control unit 32. As a result, the motor control unit 32 controls the servomotors 26Y, 26Z, and 26X so as to be in the feed position, and the fixed base 20 or the table 22 is axially moved according to the shaft feed operation.

Further, the position control unit 56 is a machine tool so that the relative position of the probe 34 with respect to the workpiece W is displaced along the X-axis or the Z-axis when the measurement operation is performed by the operator using the input unit 40. 12 is controlled.

That is, the position control unit 56 generates a measurement program for displacing the relative position of the probe 34 with respect to the workpiece W under the measurement conditions specified by the operator. In the present embodiment, as the measurement conditions, the moving direction and the moving distance from the position of the probe 34 when the probe 34 is positioned so as to come into contact with the workpiece W by the axial feed operation of the operator (at the start of measurement). It shall be specified. The moving direction is at least one of the X-axis direction and the Z-axis direction, and in the present embodiment, the Z-axis direction is specified.

When the position control unit 56 generates a measurement program, the position control unit 56 outputs the generated measurement program to the motor control unit 32. As a result, the motor control unit 32 controls the servomotor 26Z based on the measurement program, and the fixed base 20 axially moves the movement distance specified by the operator from the position determined by the shaft feed operation in the Z-axis direction. .. As a result, the relative position of the probe 34 attached to the fixing base 20 with respect to the workpiece W changes along the Z axis. At this time, the axial movement of the fixed base 20 in the Y-axis direction is stopped, and the probe 34 attached to the fixed base 20 is in an immobile state in the Y-axis direction.

The calculation unit 58 calculates the amount of change in the distance measured by the measuring device 16 based on the distance stored in the storage medium 44 at predetermined intervals.

That is, the calculation unit 58 sets the distance measured at the start of measurement as a reference, and determines when the distance set as the reference and the relative position of the probe 34 with respect to the workpiece W change along the Z axis. Calculate the difference (change amount) from each distance measured at intervals. The calculation unit 58 uses one of the distances measured at predetermined intervals when the relative position of the probe 34 with respect to the workpiece W is changing along the Z axis as a reference. It may be set and the difference (change amount) of the distance before and after the time from the other may be calculated.

When the calculation unit 58 calculates the change amount of the distance from the machining object W, the calculated change amount is output to the display control unit 54. As a result, as illustrated in FIG. 3, the display control unit 54 displays the amount of change in the distance from the workpiece W. Therefore, the operator can grasp whether or not the workpiece W is tilted.

Further, the calculation unit 58 calculates the inclination θ of the workpiece W based on the distance stored in the storage medium 44 and the position of the probe 34 at predetermined intervals.

That is, as shown in FIG. 4, the calculation unit 58 has the distance measured when the probe 34 displaced with respect to the workpiece W by the position control unit 56 is at the first relative position P1 and the second. The inclination θ of the workpiece W is calculated based on the distance measured when it is at the relative position P2 of. Specifically, the calculation unit 58 has a difference between the distance when it is at the first relative position P1 and the distance when it is at the second relative position P2, and the first relative position P1 and the second relative position. The slope θ is calculated based on the difference (movement amount) from the position P2.

In FIG. 4, the distance measured by converting the contact pressure of the probe 34 at the first relative position P1 and the distance measured by converting the contact pressure of the probe 34 at the second relative position P2 are shown. Differently, the positions of the first relative position P1 and the second relative position P2 are also different. Therefore, the inclination θ of the object to be machined W becomes larger than zero. Although not shown, when the distance and the position at the first relative position P1 and the second relative position P2 are the same, the inclination θ of the workpiece W is zero. That is, the inclination θ of the object to be machined W does not occur.

The tilt correction unit 60 controls the machine tool 12 so that the inclination θ of the machining object W calculated by the calculation unit 58 becomes small. That is, when the inclination θ of the workpiece W calculated by the calculation unit 58 is larger than zero, the inclination correction unit 60 generates and generates a correction position (coordinate information) in which the inclination θ becomes, for example, zero. The feed position is output to the motor control unit 32. As a result, the motor control unit 32 controls the servomotor 26A so that it becomes the correction position, and the table 22 moves so that the inclination θ of the table 22 becomes zero. As a result, the inclination θ of the workpiece W attached to the table 22 is corrected so as to be orthogonal to the Y axis.

Next, the tilt correction mode of the information processing apparatus 18 will be described. FIG. 5 is a flowchart showing the flow of the tilt correction mode.

When the mode for correcting the inclination θ of the object to be machined W is set, in step S1, the calculation unit 58 determines whether or not the shaft feed operation is performed by the operation of the input unit 40 by the operator. At this time, the display control unit 54 displays the distance acquired from the measuring device 16 by the first acquisition unit 50 and the position of the probe 34 acquired from the numerical control device 14 by the second acquisition unit 52. As a result, the operator can perform an axial feed operation so that the probe 34 is arranged at a desired position with respect to the workpiece W.

In the present embodiment, as a preparation for measuring the relative distance between the probe 34 and the workpiece W, the axial feed is made so that the tip of the probe 34 comes into contact with the desired position of the workpiece W. The operation shall be performed.

Here, when the shaft feed operation is performed, the calculation unit 58 proceeds to step S2, generates a feed position (coordinate information) corresponding to the shaft feed operation, and outputs the probe to the motor control unit 32. After axially moving the fixed base 20 to which the 34 is attached, the process proceeds to step S3. On the other hand, if the axis feed operation is not performed in step S1, the calculation unit 58 proceeds to step S3.

In step S3, the position control unit 56 determines whether or not the measurement operation has been performed by the operator using the input unit 40. Here, if the measurement operation is not performed, the position control unit 56 returns to step S1. On the other hand, when the measurement operation is performed, the position control unit 56 proceeds to step S4.

In step S4, the position control unit 56 axially moves the fixed base 20 on which the probe 34 is attached so that the relative position of the probe 34 with respect to the workpiece W changes along the Z axis. That is, the position control unit 56 generates a measurement program for displacing the relative position of the probe 34 with respect to the workpiece W under the measurement conditions specified by the operator, and numerically controls the generated measurement program. After outputting to the device 14, the process proceeds to step S5.

In step S5, the first acquisition unit 50 starts acquiring a distance from the measuring device 16 at predetermined intervals, and stores the acquired distance in the storage medium 44. The second acquisition unit 52 starts acquiring the position of the probe 34 from the numerical control device 14 at predetermined intervals, and stores the acquired position of the probe 34 in the storage medium 44. When the distance and the relative position of the probe 34 are stored, the process proceeds to step S6.

In step S6, the calculation unit 58 calculates the amount of change in the distance when the relative position of the probe 34 with respect to the workpiece W is displaced in step S4, based on the distance stored in the storage medium 44. On the other hand, the display control unit 54 causes the display unit 42 to display the amount of change in the distance calculated by the calculation unit 58 and the position of the probe 34 at the time of the calculation, and proceeds to step S7.

In step S7, the position control unit 56 fixes the position of the probe 34 relative to the workpiece W to the moving distance specified as the measurement condition based on the position of the probe 34 stored in the storage medium 44. It is determined whether or not the table 20 has been axially moved. Here, if the fixed base 20 is not axially moved to the moving distance designated as the measurement condition, the position control unit 56 returns to step S5.

On the other hand, when the fixed base 20 is axially moved to the movement distance designated as the measurement condition, the position control unit 56 stops the axial movement of the fixed base 20. In this case, the first acquisition unit 50 stops the acquisition of the distance, and the second acquisition unit 52 stops the acquisition of the position of the probe 34. When the stop process is completed, the process proceeds to step S8.

In step S8, the calculation unit 58 calculates the inclination θ of the workpiece W based on the distance stored in the storage medium 44 and the position of the probe 34, proceeds to step S9, and the calculated inclination θ is zero. Judge whether or not.

Here, when the inclination θ is zero, the inclination correction mode ends. On the other hand, when the inclination θ is larger than zero, the inclination correction unit 60 generates a correction position (coordinate information) at which the inclination θ is, for example, zero, and outputs the correction position to the motor control unit 32 to output the correction position to the table 22. The inclination θ of the object to be machined W attached to is corrected so as to be parallel to the moving axis. This ends the tilt correction mode. In this embodiment, the inclination θ is corrected so as to be parallel to the Z axis.

[Modification example]
The above embodiment can be modified as follows.

(Modification 1)
In the above embodiment, the display control unit 54 does not display the inclination θ calculated by the calculation unit 58, but the display unit 42 may display the inclination θ. The display control unit 54 may display the inclination θ calculated by the calculation unit 58 on the same screen as the distance measured by the measuring device 16 and the position of the probe 34, and may display the distance and the position of the probe 34. May be displayed on another screen. Further, although the display control unit 54 displays the amount of change in the distance measured by the measuring device 16, the distance measured by the measuring device 16 may be displayed together with the amount of change.

(Modification 2)
In the above embodiment, the position control unit 56 displaces the relative position of the probe 34 in contact with the workpiece W along the Z-axis direction. At that time, the calculation unit 58 determines the difference between the distance when the probe 34 displaced along the Z axis is at the first relative position P1 and the distance when it is at the second relative position P2, and the first. The slope θ was calculated based on the difference (movement amount) between the relative position P1 and the second relative position P2.

On the other hand, the position control unit 56 displaces the relative position of the probe 34 along the Y axis from the predetermined first start position until it comes into contact with the workpiece W, and in the Z-axis direction with respect to the first start position. The relative position of the probe 34 may be displaced along the Y axis from the shifted second start position until it comes into contact with the workpiece W. At that time, the calculation unit 58 processes the difference (movement amount) between the first start position and the second start position, the distance from the first start position to the contact with the machining object W, and the machining from the second start position. The inclination θ of the object to be machined W may be calculated based on the difference from the distance to contact with the object W.

(Modification 3)
In the above embodiment, the relative position of the probe 34 with respect to the workpiece W is displaced along the Z axis by a movement distance specified by the operator. However, when the object W to be machined is smaller than the moving distance specified by the operator, the measuring device 16 becomes incapable of measuring the distance. Therefore, when the measuring device 16 cannot measure, the information processing device 18 controls the numerical control device 14 so as to stop the machine tool 12, and uses the distance measured until the measurement becomes impossible. The inclination θ of the object to be machined W may be calculated.

Specifically, when the first acquisition unit 50 cannot acquire the measurement information (distance) from the measuring device 16, the position control unit 56 outputs a stop command to the motor control unit 32 by outputting a stop command. The relative displacement of the probe 34 with respect to the workpiece W is stopped. Further, in this case, the calculation unit 58 calculates the inclination θ of the workpiece W as described above based on the distance stored in the storage medium 44 and the position of the probe 34 until the first acquisition unit 50 becomes unacquirable. do.

(Modification example 4)
In the above embodiment, the calculation unit 58 is measured when the probe 34 displaced with respect to the workpiece W is in two relative positions (first relative position P1 and second relative position P2). The inclination θ of the workpiece W was calculated based on the distance. However, the calculation unit 58 may calculate the inclination θ of the workpiece W based on the distance measured when it is at two or more relative positions.

(Modification 5)
In the above embodiment, the inclination of the table 22 in the Z-axis direction or the X-axis direction is changed, but the inclination of the table 22 in the Y-axis direction may be changed. When changing the inclination of the table 22 in the Y-axis direction, the inclination is changed by a servomotor different from the servomotor 26A.

(Modification 6)
In the above embodiment, the measuring device 16 converts the contact pressure of the probe 34 in contact with the machining object W into the distance between the probe 34 and the machining object W, so that the probe 34 and the machining object W are relative to each other. Distance was measured. However, the measuring device 16 converts the time from irradiating the machining object W with light to receiving the light by converting it into the distance to the machining object W, so that the probe 34 and the machining object W are relative to each other. You may measure the distance. Further, the measuring device 16 can be applied to measure the distance by converting a parameter other than the contact pressure or time into a distance.

(Modification 7)
In the tilt correction mode of the above embodiment, the operator brings the probe 34 into contact with the desired position of the machining object W by an axial feed operation, and the information processing apparatus 18 makes the tilt θ of the machining object W from the contact position. Was calculated, and the slope θ was corrected according to the calculation result. However, the information processing apparatus 18 brings the probe 34 into contact with the desired position of the machining object W, calculates the inclination θ of the machining object W from the contact position, and corrects the tilt θ according to the calculation result. You may.

(Modification 8)
In the above embodiment, the servomotor 26, the power conversion transmission mechanism 28 including the ball screws 28Xa, 28Ya, 28Za and the nuts 28Xb, 28Yb, 28Zb are used for the configuration in which the probe 34 or the workpiece W is axially moved. rice field. The ball screws 28Xa, 28Ya, and 28Za may be replaced with static pressure air screws for the configuration in which the probe 34 or the workpiece W is axially moved.

Similarly, for a configuration in which the probe 34 or the object W to be machined is axially moved, a power conversion transmission mechanism 28 including a servomotor 26, a ball screw 28Xa, 28Ya, 28Za and a nut 28Xb, 28Yb, 28Zb includes a static pressure bearing. It may be replaced with a linear motor (motor).
